/* zoned.css — the daily puzzle's own paint.
 *
 * The owner-approved prototype's stylesheet (zoned-v3, 2026-10-01), with
 * every rule scoped under .zd so nothing here can reach the paper's header,
 * footer or any other page that shares styles.css, and every animation name
 * prefixed zd- so none can collide with one of the paper's. The colors, sizes
 * and motion are the prototype's own.
 *
 * Its theme follows the reader's phone like the prototype did, but it is the
 * GAME that turns dark (.zd), never the page around it: the paper's header
 * and footer stay the paper's.
 *
 * Served immutable for a year (the .css rule in _headers), so any edit here ships
 * with a new ?v= token on zoned.html's link. tests/test_zoned.py pins the
 * token to this file's content.
